I-amniotic fluid noma i-amniotic fluid iyimvelo yamanzi ejikeleza umntwana kusukela ekukhulelwe kwangaphambi kwesikhathi kuze kufike ngesikhathi sokubeletha. Kule ndawo, ingane ikhululekile kokubili kokushisa kanye nokuzwa okujwayelekile. Ikhemikhali iyayilondoloza ekulimaweni kwemishini, iyondla, inika umuzwa wokulondeka.
Njengoba i-amniotic fluid idlala indima ebalulekile ngesikhathi sokukhulelwa, odokotela bayayilinda. Ikakhulukazi libhekene nesibonakaliso esinjalo njenge-amniotic fluid. Ngokuvamile, ukukhulelwa kwe-amniotic fluid kumele okungenani kube ngu-500 futhi kungaphezu kuka-2000 ml.
Yiqiniso, ngosuku lwaso lokuqala kunama-30 ml kuphela, kodwa eduze kwamasonto angu-37, ivolumu ifinyelela inani eliphakeme le-1500 ml. Ngokusondele ekubelethweni, le vidiyo yehla cishe ku-800 ml. Ukwakhiwa kwe-amniotic fluid nakho kuyashintsha. Uma ekuqaleni kokukhulelwa kufana nokuhlelwa kwiplasma yegazi, ngakho-ke ngokuhamba kwesikhathi, imikhiqizo yobomi bentsana ixutshwe lapha. Yiqiniso, amanzi ahlanzwa - cishe wonke amahora amathathu, avuselelwe ngokuphelele.
Imisebenzi ye-amniotic fluid
Phakathi kokuqokwa kwamniotic fluid - amortization kanye nokuvikelwa kokulimala okunokwenzeka, usizo ekusetshenzisweni kwemithi phakathi komama nengane, ukudla komntwana, ukuthunyelwa kwe-oxygen.
Futhi ngesikhathi sokubeletha, i-amniotic fluid iyasiza ekuvuleni umlomo wesibeletho, okwenza njengendlela yokugcoba amanzi futhi "ukugcoba" indlela yokuba umntwana aphume.
Ukuhlaziywa kwe-amniotic fluid
Kwezinye izimo, odokotela bathumela owesifazane okhulelwe ukuba ahlaziye i-amniotic fluid. Le nqubo ibizwa ngokuthi i-amniocentesis futhi ihilela ukukhishwa kwesikhumba.
Phakathi kwezinkomba ze-amniocentesis:
- I-Rhesus-impikiswano phakathi komama nengane;
- ukusola ngamathambo we-chromosomal;
- osolwa ukuthi i-hypoxia (i-oxygen starvation) ye-fetus;
- uma kunesidingo sokubeletha kwasekuseni, i-amniocentesis isiza ukuthola ukuthi ukulungele amaphaphu okubeletha ekubelethweni.
Ukutadisha i-amniotic fluid kuvumela ukwazi ubulili bomntwana ozayo , iqembu lakhe legazi, izifo ezingase zifake izifo. Kodwa lokhu kuhlaziywa kungenziwa kuphela kusukela ngesonto eli-14 lokukhulelwa.
Kuyinto engavamile kakhulu, kodwa kwenzeka phakathi kwabesifazane abakhulelwe njengalezi zifo njenge-embolism ne-amniotic fluid ( embolism yamniotic fluid ). Lokhu kwenzeka uma uketshezi kungena emgodleni wegazi lomama bese kuphazamisa amagatsha omshini wesimopho wesifazane. Ngama-70-90% amacala aphela emiphumeleni ebulalayo. Ngenhlanhla, into efana naleyo ivela ku-1 kwangu-20-30 yeziganga eziyinkulungwane.
